Boxster 986 particles in oil filter

LTFT and STFT are fuel trim stats, (Long term and short term fuel trim) as I understand it. What I see that seems odd is the coolant temp. is that 92 celcius= nearly 200 degrees Fahrenheit?

Not at all odd, most of these cars with the factory thermostat are running 210-215F.

interesting. I have only referenced the drivers gauge for temp, never seen mine step up above about 185 on a hot summer day, fans blazing. I will play with my duremetric and see if this is different. I just replaced the thermo with a 72C, but the driver gauge only shows about a 3-4 degree lower (183 was "normal" now it hits 180 and sticks)
thanks!

I just replaced my OEM thermostat with a low temp thermostat.
I then took the car on a 297 mile run with my scanner plugged into the OBDII port.
This allowed me monitor the temps that the ECU was seeing and compare readings to the dash display.
Ambient temps were from 61 degrees in the morning to 93 degrees in the afternoon.
Coolant temps ran from 183 -205 degrees depending on engine load, ambient temp, road speed, and RPM.
Coolant temps reported by the scanner corelated very closely to the dash gauge.

I have done this same test with the OEM thermostat. on the same 297 mile run.
Coolant temps in that test ran 5 degrees higher through the range.

Also I don't think the fans kick on until around 196-200 degrees. At least mine don't. Mine is a 2000S
Just as an edit to this: I looked up the trigger temps for the fans.
Low speed kicks on at 206.2F high speed kicks on at 215.6F

Normal operating temp for the conditions.
Car is sitting still and the fans have not kicked on yet.
Normal temp for just about any car I can think of for the conditions.

Agreed. In most European cars fan switch turns on at 92 C and off at 82 C, so at idle or in heavy traffic coolant temperature varies between these two values.

Foxwell looks like a good deal. What`s the advantage of Durametric over this? I`ll need to buy one soon too.

Thanks everyone for the help it looks as if my very cheap (£14) code reader isn't going to be any use on this. The temp is about right for my car (runs hot in traffic or if not on open road) but I have not noticed the side engine cooling fan starting up for ages.

Strange thing is the car is running exactly as it always has and I got it home after only 4 miles (to test it and warm it up) thinking it is going right.

A contact of mine (ex Porsche engine builder) in UK suggested that there are other green rubber items it may be; such as spark plug tube seals or 2 sump round cavity things and these can get broken up?
One of mine did have a leak and 2 tubes came out on the coils doing a spark plug change recently.

I own both.
Personally I don't see that Durametric has an advantage over the Foxwell.
The Foxwell will do everything that the Durametric enthusiast model will do.
My Foxwell was around $175.00 shipped.
I think Durametric is around $350.00 for the enthusiast model and around $750.00 for the professional model.

Durametric: you need a laptop
It is Porsche specific=it only reads Porsche
The enthusiast model is limited to use on Three vin numbers
some info is a little difficult to follow such as the way RPM ranges are laid out for fuel trims

Foxwell:
Standard scanner= no laptop needed
it comes loaded with what ever manufacture specific program you choose
You can add additional manufactures for around $60.00 per manufacture.
Your not limited to how many different Vins you connect to.
You can do the normal scans, live data, freeze frame, graphs etc. on any OBDII compliant system.
You only need manufacture specific programs to access manufacture specific codes or functions.

Screen layouts are of course different between the two.
Durametric is typical computer layout with various folders
Foxwell is typical OBDII scanner layout.
I think Foxwell is a very good buy for the money

Thanks for the useful info . I think I`m gonna get one.
